Note on Generalized Janus Configurations
Bin Chen, Zhi-bo Xu, Chang-yong Liu
We study several aspects of generalized Janus configuration, which includes a theta term. We investigate the vacuum structure of the theory and find that unlike the Janus configura…
Semi-classical strings in AdS_4*CP^3
Bin Chen, Jun-Bao Wu
In this paper, we study the semi-classical strings in AdS_4*CP^3 spacetime. We construct various kinds of string solutions, including the point-like, circular, folded and pulsating…
D1-D3 (or ) Systems with Fluxes
Bin Chen, Xiao Liu
In this article we study D1-D3 (or ) brane systems with generic constant electric and magnetic fluxes in IIB string theory. We work out all possible supersymmetr…
-vacuum and inflationary bispectrum
Wei Xue, Bin Chen
In this paper, we discuss the non-Guassianity originated from the -vacuum on the CMB anisotropy. For -vacuum, there exist correlation between points in the acausal two patche…
